Hmmmm... you mean 80C, right? 80F is not bad at all, that's WELL within tolerance. 80C is... WAAAAAAAAAAAAY too hot. Definitely get some ASIII on there, and make sure that old heat pad has been scrubbed off good with isopropyl alcohol before you put on the ASIII. See what kind of temps you get then. If that does not lower it to below 45 or so, consider investing in a Swifty or a Glaciator or something of the like.
